Lilac bushes are known for their fragrance that floats on the spring air and their elegant, beautiful flower panicles. Loved by generations of gardeners, lilac shrubs are found on many older homesteads and in modern gardens and landscapes. Thanks to modern breeding efforts, lilacs are now available in many flower colors including pink, white, purple and yellow, and in different sizes, including compact lilacs. Lilac flowers attract hummingbirds and butterflies, and they look lovely in a vase. Lilac bushes can be planted in groups to form an informal flowering hedge or planted near walkways and entrances where visitors can delight in their fragrance and beauty.
